RZR are crap wheels in my opinion and I would fight really hard to not let any friend of mine waste their money on those wheels. They are light, but there are so many better options that are really close in weight that are both more aero and stiffer. There just isn't any upside to them that I am aware of. Search the web for the Lew wheels since they are exactly the same wheel. I remember a photo of one of these wheels from a crash in a pro race a few years back where upon impact the wheel basically exploded. Tons of info out there and it all basically says that they are a horrible wheelset. Lightweights are really nice, as are the Mavic CCU's. You can't go wrong with a set of Enve rims built to a set of Tune (or other nice) hubs. If you care about aero then go with Hed or Zipp. The new Enve wheels designed by Simon Smart sound interesting, but there is no info out on them yet as they are not yet available.
It's all a matter of what you want though and what's important to you.
Have you ever wondered if there was more to life, other than being really, really, ridiculously good looking?
